Hawkeye and Trapper prevent a GI from marrying a call girl who has TB, whilst trying to help a Korean soldier join his pregnant wife. Radar, of course, provides his usual invaluable help.

Radar is driving Hawk, B.J., Sherman, and Frank in a bus back from a "medical conference" when they get lost. They stop to see if they can find anything they recognize. When they decide to turn around, they find that the bus does not want to start. Radar goes off in the middle of the night for the latrine, and does not immediately return. Stricken, Hawkeye wants to set out to find him, only to be stopped by Sherman. An injured Korean surrenders to get medical help from Hawk and B.J.. Upon Radar return, the Korean helps repair the bus and get them out of danger.

Instead of turning him in as a prisoner of war, Hawkeye and B.J. pull some strings to get a wounded North Korean surgeon a spot on the staff.

Hawkeye and BJ lose their way while rushing urgently needed antibiotics to the 4077th, which is wracked with low-mileage Thanksgiving turkey-induced salmonella. Wandering back to M*A*S*H, the pair are found by a peculiar North Korean soldier.

The Army tries to get a North Korean pilot to defect, and Charles gets a rude shock when he falls for a French nurse with a Bohemian past.
